Abstract
This study was conducted to assess the morphological, chemical and genetical diversity among eight carob female strains through two successive seasons (2011 and 2012) in Bourg El-Arab region of Alexandria governorate. The analyzed strains were highly significant for characters of pod weight fruit shape. Strains 2 and 4 always detected the highest approximated yield; this yield ranged from 26 to 28Kg/ tree. The obtained resultsof chemical composition (protein, sugar, tannin, total sugar, flavonoid and total phenol content) exhibit significant differences.
RAPD primers tested with the DNA of the eight carob strain, revealed percentage of polymorphism ranged from 10% (OPZ19) to 84.62% (OPA10). Moreover, eleven unique markers were identified with the tested strains. Dendrograms based upon chemical and genetical data clustered almost the same strains in the same group reflecting a relationship between chemical and genetical characteristics.
